1.3 EFI (old)City is pretty fast. Never raced with the newer model but older one feels faster.
On paper old city has 92HP and a curb weight of around 900kg whereas the newer city is around 200kg havier with L13Vtec producing around 99HP. 1.5 version has an edge since it is about 110HP.
An old city with D15 motor has a definite edge. Besides it handles great and is best on attacking corners.
